Enriching Web Services Tags to Improve Data-Driven Web Services Composition

Due to the large number of existing services and complexity of manual composition, automatic service composition is provided to enable automatic search of the service compositions for the given queries. Many solutions for automatic service composition have been developed, including integer programming, graph planning, artificial intelligence, and so on in this paper, a heuristic method is proposed to improve the data-driven composition of web services by enriching tags based on tags semantic. To do so, firstly, useful information on web services is collected from various sources and is turned into collections of tags. In the next step, using the hierarchical clustering algorithm, the tags are clustered based on semantic similarity. Thereafter, for services which do not have enough tags, enrichment of the tag is carried out and finally, using an algorithm, composition solutions based on QoS parameters are extracted, which can formulate user targets or even provide potential compositions. Moreover, a series of tests were conducted on the web services, which validate the efficiency of the proposed approach. The experimental results confirm the effectiveness of the proposed service composition method and high quality of tag enriching strategies.

Formal Specification of Adaptable Semantic Web Services Composition

This article proposes a formal specification method for Web services composition based on context-aware semantic planning graph technique. The authors first use a graph planning technique to conceive an adaptable semantic Web services composition. They use an ontology based context model for extending Web services descriptions with information about the most suitable context for its use. Then, the composition problem is transformed into a semantic context aware graph planning problem to build a set of best-composed Web services based on the user's context. Because of the error-prone nature of the Web services composition process, and with the integration of context information in this process, the complexity of Web services-based systems is increasing, hence the need for formal specification and verification approaches of such systems. The authors seek to use CCA calculus, to formalize Web services composition expressed in terms of adaptable OWL-S, and transform the description of workflow patterns into the description patterns in terms of CCA, a calculus for context-aware ambients.

Contribuição do infográfico jornalístico para a comunicação em saúde / Contribution of Journalistic Infographic for Health Communication

ABSTRACTThe purpose of this article is to point out how the computer graphics can contribute to the organization of reports on health in printed vehicles, contributing to the strengthening area of health communication. To show it, the second year students of Journalism an educational institution of Maringá-Paraná-Brazil, who attended the course Graph Planning, were asked to analyze the design of a page of a brazillian newspaper Folha de S. Paulo, which was included a computer graphics. We have seen that this journalistic language offers several possibilities to Communication and Health Promotion, because joins verbal and imagery to arrest the content, helping change people habits from the moment that are increasingly present in the mass communication vehicles.RESUMOO objetivo deste artigo é apontar de que forma a infografia pode contribuir para a organização de reportagens sobre saúde e para as possibilidades de apreensão da informação pelo leitor de um veículo impresso, contribuindo, desta forma, para o fortalecimento da área da comunicação em saúde. Para dar conta deste objetivo, os alunos do segundo ano de Jornalismo de uma instituição de ensino de Maringá, que cursavam a disciplina de Planejamento Gráfico, foram solicitados a analisar o design de uma página da Folha de S. Paulo, onde estava incluída uma infografia sobre o Mal Vaca Louca. Viu-se que os quadros aproximam a linguagem jornalística da prática da Comunicação e Promoção da Saúde, visto que ofere-cem várias possibilidades, verbais e imagéticas para apreensão do conteúdo, podendo mudar hábitos a partir do momento que estão cada vez mais presentes nos veículos de comunicação de massa.
